DOOR LATCH.

Application filed February This invention relates generally to latchesdesigned particularly for use with vehicle doors and consists of certainnovel features of construction, combinations and arrangements of partsas will be more fully de scribed and particularly pointed out in theappended claims.

in the accompanying drawings;

Figure 1 is a horizontal sectional view through a vehicle door with alatch embodying my invention attached thereto.

Figure 2 is a perspective view ofthe latch.

Figure 3 is another perspective view of the latch.

Figure is a side elevation of the latch with. the outside cover plateremoved.

Figure is a side elevation of the latch with the inside cover plateremoved.

Referring now to the drawings in which like characters of referencedesignate corresponding parts throughout the several views, the numeral1 designates a door, preferably of a vehicle body, having a pillar 2provlded at its inner edge with a channel-shaped portion 3 whichconstitutes a run-way for a ver tically movable glass panel 4-.

In order that a latch may lie-mounted and operated upon the pillar 2without interfer- .ing with the vertical movement of the glass panel i,1 preferably provide a case plate 5 that is preferably U-shape in crosssection and that preferably straddles the channel-shaped guide-way 3. Asshown, the inner section 6 of the case plate preferably supports aswingingly mounted latch bolt 7 and the mside operating means therefor,while the outer section 8 preferably supports the outside operatingmeans for the bolts.

In detail, the bolt 7 is preferably stamped from sheet metal and isprovided with an upstanding shank portion 9 and a forwardly extendinsrhead 10. As shown, the shank 9 is preferably provided at its lower endwith hub 11 that is journaled in aligned openings in the inner caseplate section 6 and cover plate 12 secured thereto, while t-he head ispreferably beveled at its outer end and 1s adapted to engage a suitablekeeper 13 upon a door iamb of the vehicle body.

In order that the bolt may be retracted from either the outside or theinside of the door, the shank 9 is preferably provided at diametricallyopposite points of the hub 11 with torwardly andrearwardly extending 16,1925. Serial no. 9,685.

arms 14 and 15 respectively which are adapted to be actuated by a rollback 16 upon the outer section 8 of the case plate, and a lever 17 uponthe inner section 6 of the case plate. As shown, the roll baclr 16 has ahub 18 journaled in aligned openings in the outer case plate section 8and cover plate 19 secured thereto and is provided at its forward edgewith a lateral extension 20 that extends across the transverselyextending portion 21 of the case plate, and is normally engaged by acorresponding lateral extension 22 of the arm 14. Any suitable means maybe engaged with the square opening 23 in the hub 18 for rocking theroll-back 16 so that the lateral eXtension 20 thereof will raise thelateral extension 22 of the arm 14 and cause the latter to retract thebolt. The lever 17 normally engages suitable spaced lugs 24 and 25respectively on the forward edge of the arm 15 and is preferablyprovided at its lower end with a flat rounded head 26 that is pivotallymounted on the inner section (3 of the case plate between the shank 9and rearwardly extending arm 15. Any suitable means such as the helicalspring 27 engaging the rearwardly extending arm 15 may be employed fornormally holding the bolt head 10 in projected position and also forholding the lateral extension 22 of the arm 14 in operative posi tionwith respect to the lateral extension 20 of the roll-back 16. Thus, withthis construction, the roll-back 16 may be actuated from the outside ofthe door to retract the bolt without affecting the lever 17 and thelatter may in turn be swung to the rear against the arm 15 withoutaffecting the rollback. In order that the outside operating means may berendered inoperative from the outside of the vehicle, I preferablyprovide a dog 28 that is pivoted on the outer section 8 of the caseplate and is adapted to swing behind a lug 29 on the roll back 16 toprevent the upward swinging movement of the extension 20. This dog 28 isnormally held out of the path of the lug 29 against the struck out lug80 on the case plate section 8 by means of a coil spring 31 anchored onthe case plate section 8 and may be moved by any suitable means intooperative dogging position. As shown, the dog 28 is preferably actuatedby a suitable cam 32 rigidly secured to the rotatable cylinder 33 of anauxiliary lock 3% which is preferably anchored. in a tubular housing 35projecting laterally from the cover plate 8 and any suitable means suchas the screw 36 threadedl Y en a m the laterall attachin b b a: V a

flan 'e 39 of the case Jlate ma be em lo ed .forholding the lock 3dwithin the housing 35.

In order that the outside operating means may be rendered inoperativefrom the inside of the door, 1 preferably provide a dog- 10 that isadapted to be moved by the inside operating lever 17 intooperativedogging' position behind a shoulder 11 of the boltshank 9 forpreventing the bolt from being retract- "edfro'inthe outside of thedoor. As shown,

this dog 40 is preferably pivoted on a pin 42 anchored upon the-innersection 6 of the case plate and is normally held outof the pathof thebolt shank by means of a suitable spring a3 secured to the case platesection 6. More- 'overthe forwardly extending portion 10 of the bolt isprovided'at its upper edge with a recess portion 4.4 to receive the dog10 when" the bolt is retracted. W'ith this construction, the dog may bedetachably held in operative dogging position by means of the lever 17.As shown, a suitable leaf spring is' anchored upon the inner face of thecover plate 12 andis provided at one end with an inwardly extending rib46 that is engageable with a suitable depression 47 in the outer face ofthe'lever 17 when the latter is in its for whereu Jon the sarin 18 willautomaticall t) move the dog 10 upwardly out of the pathof the shoulder4-.1. The roll-back 16 may then be operated from the outside of the doorif desired for retracting the bolt. I

To prevent the lever 17 from rattling, 1 preferablyprovide a suitablespring a8 that is anchored upon the inner section 6 of the case plateand consequently holds the lever 17 against the spring-pressed dog 40and rib 46 of the'leaf spring -15. Thus, the spring 4-3 as well as thesprin g cooperates with the spring 18 for normally holding the lever 17against rattling.

From the foregoing descriptlon, it will be readily apparent that a latchof this type may be mounted upon a' door pillar having a very smallcross section, consequently the vision of the occupants of thevehicle'is materially' increased. Moreover, the arrangement is such thatthe bolt 10 may be retracted from the outside of the door withoutinterrupting the vertical movement of the glass panels. It will alsobe'apparent that the outside operating means may be operatedindependently of the inside operating means for retracting the bolt. Itwill also be noted that the inner cover plate 12 cooperates with theinner section 6 of the case plate for holding the lever 17 in properposition between the shank 9 and arm 15. Moreover, a lug 50 is providedupon the roll-back 1G for engagement with a struck out lug 51 on theouter.

section 8 of the case plate for limiting the downward swinging movementof the rollback 1 6.' Inasmuch as the spring27 normally urgesthe bolt 10forward, it will be readily apparent that the forward swinging movementof the bolt is limited by the engagement of the lateral extension 22with the lateral extension 21 of the roll-back 16.

While it" is believed that from the fore going description the naturesand advantages of my invention Will be readily apparent, l

desire to llLVGli? understood that I do not limit myself to what isherein shown and described and that such changes maybe resorted to whendesired as fall within the scope of what is claimed.
